Option 2:
Remove the pivot plate from the jig by removing the three
retaining screws. Remove the original router baseplate and place the router
on top of the plate. Note the position of the router handles and other fittings.
The router should be rotated until the handles and fittings will not interfere
with the set plate when the router base is pivoted during use. The opening
in the pivot plate should be centered on the router bit opening. If your router
plate will accept a bushing, use the bushing to help you center the router on
your pivot plate.
Carefully mark the location of router mounting holes. Drill
the mounting holes and countersink them so the screw heads are just below
the bottom surface of the pivot plate. Reinstall the pivot plate into the jig
and tighten all the screws. The pivot screw is secured with a special nylon
lock nut. Tighten the screw firmly, then back off ¾ turn to allow smooth
movement of the pivot plate.
Setting dado width to match material
To set the dado width, select the set plate that
matches the diameter of the bit used. Select ¼
″
for dados
from ¼
″
to ½
″
wide. Use a
⅜″
bit and set plate for dadoes
from
⅜″
and larger.
Install the set plate and push the pivot plate against
the left stop as shown; place a sample of the material
between the straight portion of the pivot plate and the set
plate. Press the set plate trapping the material between the
pivot plate and the set plate.
Compensation for runout and adjusting fit.
There is an additional adjustment that compensates for variation in routers, runout, and
degree of desired fit. Set plates are adjustable left to right by a small amount. There is an arrow
on the set plate. Moving the set plate in the direction of the arrow tightens the dado slightly. Moving
it to the right loosens the cut. If your test dado it too tight, move the set plate to the right. If your
dado is too loose, move the set plate to the left.
NOTE: There is a reference slot in the base plate and a notch cut in each set plate to allow
a visual reference of the setting. You may have to practice a couple of times, but you will soon get
the hang of it!
We recommend you make your initial cut with the set plate in the “tight” position.
You can always make a small adjustment and make another pass if the dado is too narrow.
Press the set plate against the material and tighten both thumbscrews snugly. Once set for a given
thickness, all additional dados should be exactly the same width.
ALWAYS TEST THE FIT IN A SCRAP OF WOOD TO ASSURE YOU HAVE PROPERLY
ADJUSTED THE SET PLATE. SOME VARIATION CAN EXIST AND CORRECTIONS ARE EASILY
MADE BY ADJUSTING THE LEFT TO RIGHT POSTION OF THE SET PLATE A SMALL AMOUNT TO
GIVE A TIGHTER OR LOOSER FIT.
Insert a sample of the wood between the set plate
and the pivot plate. Press gently and tighten the
knobs snugly. Slide set plate left or right to adjust
cut.
Use the original baseplate to
mark the pivot plate.
